Three men were found dead on Sunday at a Pennsylvania Turnpike toll booth west of the state capital of Harrisburg, authorities reported, and local news media reported that at least one of them was a toll booth collector who had been fatally shot.

Fulton County Coroner Berley Souders confirmed that three people were found dead at around 7:15 a.m. All three victims were males, he said. He declined to provide additional information.

At least one toll booth operator at the turnpike's Fort Littleton exit in Fulton County, about 65 miles west of Harrisburg, was fatally shot in what appeared to be an attempted robbery, turnpike officials told local media.

None of the victims have been identified. Souders did not say whether any of the victims were toll booth operators.

State Police were in charge of the "complicated investigation scene," a state Turnpike Commission spokesman, Carl DeFebo, said in an interview.

Cash is accepted at most Pennsylvania toll booths, but a growing number are cashless, according to the Turnpike Commission.
